Create an oracle card with Waves Oracle

Only authorized users can create an oracle card. Authorization is performed using Waves Keeper.

The account can create no more than one oracle card.

If the authorization is done through a test network account, the oracle card will be created in the test network. If the authorization is done through an account from the main network, the oracle card will be created in the main network.

Create an oracle card

  1. Determine which Waves account you will use to create your oracle card. This can be an existing account or a newly created one. Use the instructions to create a new Waves account.
  2. Install Waves Keeper if this extension is not already installed.
  3. Go to Waves Oracles and log in.
  4. Select Create an oracle.
  5. Fill in the fields of the oracle card registration form.
  6. Click Create.
  7. Confirm the transaction in Waves Keeper by clicking Approve.
